This machine pulls and draws alloy steel bottle flans with high strength from a wallthickness 4.5mm down to 2.5-3mm in cold conditions. This machine applies a hydraulic 
drive and operates stably. The drawing is done in one cycle without any deformation, 
wrinkling or cracking. After drawing, the material is smooth and shining on both inside 
and outside surfaces. This machine is exclusively designed and manufactured for the high-strength and thin-walled 
CO2 fire extinguisher (material is 35CrMo alloy steel) of a new generation in both domestic 
and overseas markets. It has been used for many exclusive export-oriented enterprises. 
The product features high qualification rate, high automation and high speed. It only takes 
30 seconds to pull and draw each bottle flans on average. The product is an essential device 
for export-oriented steel bottle manufacturers
